ChenDe Alloy
Superior Electrical Conductivity of Silver Contacts
Silver contacts offer the highest electrical and thermal conductivity among metals, effectively minimizing contact resistance during frequent switching in relays. This ensures stable current transmission, reduces heat buildup and power loss, making them ideal for high-performance applications in switch relays.
ChenDe Alloy
Excellent Arc Erosion and Anti-Welding Resistance
Silver alloy contacts (such as AgNi or AgSnO₂) excel in resisting arc erosion and welding under high inrush currents or inductive loads. This significantly extends contact life, often achieving hundreds of thousands of operations, and enhances reliability in demanding scenarios like appliances and automotive relays.
ChenDe Alloy
Mechanical Strength and Support from Copper Components
Copper parts serve as the base material and structural support in switch relays, providing excellent mechanical strength, conductivity, and heat dissipation. Often riveted or welded with silver contacts, copper optimizes cost while maintaining overall performance balance.
ChenDe Alloy
Enhanced Oxidation and Wear Resistance in Composite Design
The composite structure of silver contacts on copper bases improves anti-oxidation and wear resistance. Even in arcing environments, the conductive silver oxide layer maintains low resistance, ensuring long-term reliability and reducing failure risks in relays.
ChenDe Alloy
Precise Circuit Control and Efficient Heat Management
Silver contacts handle precise opening and closing of circuits, while copper components ensure structural stability and superior heat dissipation. This combination is widely used in household appliances, automotive systems, and industrial controls, boosting safety and operational efficiency.
